Description
Electron beam-physical vapor deposition (EB-PVD) is a widely used technique for depositing thermal barrier coatings (TBCs) on metal substrates for high temperature applications, such as gas turbines, in order to improve thermal efficiency. As particularly, it is necessary to evaluate how the thermal conductivity of yttria-stabilized zirconia (YSZ) coatings is affected by processing conditions during EB-PVD. In this work, we calculated the thermal conductivity of YSZ coating layers deposited on dense YSZ substrates based on theory. This work also addresses the influence of processing conditions (especially substrate rotation speed) on microstructure during EB-PVD and its influence on the thermal conductivity of zirconia coating layers.
